You asked if The Urantia Book is a bible for those who read it, as Scripture is for Christians. I will do my best to answer your question.

Many Urantia Book readers come from the Christian traditions. When they find The Urantia Book, they are oftentimes relieved to have found a volume of information that comes from God and his government, but that does not have the same sort of caveats that come with Holy Scripture, e.g., that it is inerrant or that it must be believed without question. I would suspect that most readers do not treat The Urantia Book as a sacred book. The Urantia Book teaches that the only “sacred” thing about our religious life is the relationship that we develop with the personal God that is revealed in its pages.

I feel sure that among Bible- and Urantia Book readers there may be a similarity in that each of us see our text as being a source of comfort, wisdom, guidance, and information.

Following are some similarities and some differences between the Bible and The Urantia Book:

The Urantia Book is like the Bible in that it is arranged in “chapters,” or Papers.

Unlike the Bible, all Urantia Book papers’ authors are listed, and all are non-human personalities.

Like the Bible, The Urantia Book begins with the study of God and his creation.

Unlike the Bible, The Urantia Book reveals God’s true nature and personality in depth and detail – and this is a newer revelation of those truths that upsteps our understanding of God to include his loving nature that was revealed by Jesus.

Like certain parts of the Bible, The Urantia Book is replete with the history of our world; Adam and Eve, the Garden of Eden, Noah’s flood, the Lucifer rebellion, the evolution of tribes and peoples, e.g.,. All of the parallel Biblical stories are covered, and yet, they are, again, greatly expanded. All the gaps in our knowlege of these events are filled, so that we gain a true and complete picture of earth’s history, and God’s constant involvement with it.

Like the New Testament, The Urantia Book chronicles the life and teachings of Jesus; however, it is quite unlike the Bible in many respects, primary being that in The Urantia Book we learn the life of Jesus from his pre-existence, through infancy, childhood, adolescence, young manhood, ministry, and all the way up to his death, resurrection, ascension, and his post-existence status. His life is narrated in a week-by-week, and oftentimes day-by-day series of events. All of the Bible stories of Jesus’ life are parallelled in The Urantia Book, yet greatly expanded and presented as a complete story, and in superb context. His true mission is thoroughly explored and outlined, and in his life story, we see this mission-to establish the kingdom of God and to reveal his loving nature to the world-beautifully fulfilled. 

The main themes of The Urantia Book are:

Part I – God and his reality, nature, personality; God’s immense creation, its organization and administration and the personalities who inhabit it.

Part II – The “local” universe in which we live, its organization and purpose, and the resident personalities; events that affect the normal progression of worlds like ours, and how our world is unlike those normal worlds.

Part III: The exhaustive and complete history of our world – astronomical, geological, evolutionary, civilizational, spiritual. 

Part IV: The complete life and teachings of Jesus, restated in detail by celestial eyewitnesses, and for the enlightenment of all who want to know more about Jesus – who he really is, what his life really was like and what his teachings actually were.

Those who read and study The Urantia Book soon learn that the information contained is just that – information. It is not thought to be inerrant, nor is it meant to take the place of any other spiritual text. The information is vital information, however, and very useful for anyone who wishes to expand their knowledge of God, of the world, and of Jesus. In addition, the information within the Urantia Book can be adopted by the individual and actually used to create a world-view – a universe view of reality that can assist the student in navigating the sometimes turbulent waters of modern life.

The Urantia Book can actually clarify and enhance many of the vague and difficult concepts of the Bible as well as other sacred texts. The Bible, like all literature, is subject to interpretation and The Urantia Book can help tremendously with this because it fills in many of the gaps.

For example: The Bible does not explain the one-time existence of the many different types of dinosaurs, nor the long geophysical evolution of this planet. It does not explain the long evolution of the human species nor the many civilizations that have existed on this world. It does not explain how Cain, if he were a child of the first humans on earth, could find a wife in “The Land of Nod.” It never mentions what happened to Joseph, the father of Jesus, nor does it give any detail regarding the diversity of material and spiritual life that exists in the cosmos.

Although The Bible is a wonderful repository of spiritual truths recorded over the ages, it is by no means an end of God’s instruction to humankind, and neither, for that matter, is The Urantia Book. The Urantia Book is, however, the newest and most significant revelation of God to mankind since the times when Jesus of Nazareth walked the earth.

“The [Urantia] papers, of which this is one, constitute the most recent presentation of truth to the mortals of Urantia. These papers differ from all previous revelations, for they are not the work of a single universe personality but a composite presentation by many beings. But no revelation short of the attainment of the Universal Father can ever be complete.” (The Urantia Book, Page 1008, 92:4.9)
